Embodiment Construction

[0017] The structure of a card-type indoor ceiling-mounted broadband antenna provided by an embodiment of the present invention is as follows: figure 1 as shown, figure 1 is a side view of the antenna, including:

[0018] The circuit board 1 is the main body of the antenna, and is the core of the entire antenna, and is used to realize the function of the antenna to transmit and receive electromagnetic wave energy. Antenna radiating elements and radio frequency connectors are attached to it, which is the basis for the realization of the entire antenna structure. When the transceiver transmits, the radio frequency current is fed into the antenna circuit board through the connector, and the circuit board converts the radio frequency current into electromagnetic waves and transmits them to the space; when the antenna receives the electromagnetic waves, an induced current is generated on the circuit board, and the current passes through the circuit The board and connectors go int...

Abstract

The invention discloses a card-type indoor top-absorbing wide band antenna, which comprises a circuit board which is used to receive and transmit the energy of electromagnetic wave, a radio frequency connector which is arranged on the opposite side of the circuit board, is welded with the circuit board, and is used to be the interface for connecting the antenna and other equipment, and a medium nut which is used to fix the circuit board and the radio frequency connector on an indoor ceiling. The card-type indoor top-absorbing wind band antenna is used on an indoor wireless signal network cover, which has the advantages of small volume, light weight, low height and simple and convenient processing. The card-type indoor top-absorbing wind band antenna is printed on the circuit board, which adopts a symmetry dipole mode, does a step impedance conversion optimization for oscillators, and enables the antenna to work on a wide band which is bigger than three frequency doubling. The card-type indoor top-absorbing wind band antenna solves the shortcomings of bad concealment of a traditional indoor top-absorbing antenna which influences indoor decorated environment.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a card type indoor ceiling-absorbing broadband antenna. Background technique [0002] The indoor ceiling antenna is an antenna used for indoor signal coverage of wireless communication. It is generally installed on the ceiling to provide wireless signal coverage for an area with a radius of tens of meters centered on it. Plate antennas are used for outdoor signal coverage, with high power, strong signal, and long-distance coverage; while indoor coverage, such as venues, hotels, office buildings, movie theaters, and residential buildings, requires indoor distributed systems to cover, so absorbing antennas are used. Small antenna, beautiful appearance, does not affect the indoor view. [0003] Traditional indoor ceiling antennas are made of metal reflectors and vertical metal cylindrical or conical oscillators to radiate signals. The antenna has a plastic protective cover for pro...
